The Mzora Stone Circle is a huge megalithic monument in Morocco and is in fact the largest stone ellipse in the world. Mzora and the Egyptian Nabta Playa site are claimed to have used the same construction methods that Alexander Thom has shown to have been used by the British megalith builders.*A recent article by Sarah P. Young claims that “The circle is constructed using a Pythagorean right angled triangle with the ratios 12, 35, 37 and this is the same method used by 30 megalithic stone circles in Britain alone. Other similarities in construction and proportions exist such as the use of the so called ‘megalithic yard – a unit of measurement which seems to have been universally employed across Europe – and evidently even further afield” (g)*
Although no formal claim has been made for any connection with Atlantis, the supporters of the idea that the megalith builders were Atlanteans see the complexity of the Mzora site as further justification for their opinion. A July 2018 paper(f) links the ancient Berbers with Mzora and as the Berbers occupied territory described by Plato as Atlantean (Timaeus 25a-b & Critias 114c), Mzora may also be legitimately described as Atlantean.
James Mavor, better known for his research at Santorini, surveyed the Mzora site in the 1970’s. Bob Quinn visited the site in 1982 and was struck by its similarity with Newgrange. Robert Temple discusses the site at length in his Egyptian Dawn. Dale Drinnon has an illustrated blog on the subject(c).
John E. Palmer visited and surveyed the site in 1978 and subsequently wrote an article for Kadath magazine, unfortunately in French only. He reported that extensive damage was done to the site by ‘archaeologist’ César Luis de Montalban with excavations in 1935-6(d) and that many of the stones have been broken by ignorant Islamic extremists.
In 2011, Graham Salisbury gave coordinates for the site and offers a history of Mzora in a longer article(b).
There was also a French site, which had a number of images of the Mzora site(a).
